Cell Progress Update 2

[spencyg]

I just took the cell apart after running it for a constant 72 hours of conditioning. I'm not sure what I was expecting, but I was quite surprised to see that my hydrodynamics inside the cell caused quite a lot of commotion. I had arranged the cell so the 1/2" diameter passages were in opposite diagonals, hoping this would promote significant agitation of the plate surfaces. All was good when water came in at the bottom and left at the top, but when water came in at the top and left at the bottom, there was probably a 3 sq in. void of the conditioning haze in the upper corner across from the input port. In retrospect (hindsight being 20 20), this makes sense. I wasn't pumping the fluid at a high rate, so there would be no reason for the fluid to occupy these corners. I think I'm going to modify my method of assembly a bit, and poke a couple small 1/4" holes at the top of each plate (opposite the 1/2" ports). The 1/2" ports will be assembled so they are always on the bottom, but staggered left and right. This will cause the water to work a bit, and the ports at the top will ensure complete cell filling. I just borrowed a 24V power supply, so I'll put this monster back together, and re-condition with the new setup. I still won't have a way of capturing gas output until sometime next week.

Spence,

Your cell looks awesome. Nice looking bubbler. Just curious how your bubbler functions? Is it top pop off design?

The gas separator doesn't act as a bubbler. The cell is pumped, and the separator breaks the gas from the electrolyte, allowing it to be collected, and the electrolyte to be recirculated. After the separator is a standard bubbler which will most likely be made of PVC plumbing parts.
